Greenhills NCT Centre Tallagh, hard to find?

I usually go to Northpoint, but due to needing to do a re-test tomorrow, I have to go to Greenhills. I've had a look on google streetview and can't find it based on the directions on the NCT site (scroll down and click on Greenhills). I imagine it will be a big hard to miss place, though it doesn't show up on street view

Note to mods- I stuck it here rather than in the Dublin city forum as I felt the question would be quicker answered by motor fans. I have to be there at 8 tomorrow morning

Coming from the Tallaght by-pass...continue all the way down the Greenhills Road until you come to a Topaz garage...it's the right turn directly after that...then continue all the way down through the industrial estate and it's on the left :]

You'll be pleased to know I passed the re-test with flying colours, after failing a re-test yesterday, even though no work was done on the car at all. Guess the guy from yesterday was just a jerk (mechanic said the same yesterday, but in a lot less nicer way).
